Altered States - Research

I was sent a link to this trailer by my tutor, it looks like a pretty crazy film, it would be interesting to watch when I have some spare time. The part of this trailer which is of use to me is 1:47 in, although it only last for a few seconds this shot attempts to show a camera traveling through the retina and down the optic nerve. The 1980 sci-fi horror directed by Ken Russel written by Paddy Chayefsky follows the exploration of William Hurt as Eddie Jessup, a scientist obsessed with discovering mankind's true role in the universe. He subjects himself to a series of mind bending experiments using a sensory-deprivation chamber and taking hallucinogenic drugs, Jessup hopes to explore different levels of human consciousness, but instead is devolved into an apelike monster.
